Structure of the classical cephalosporins. The cephalosporins (sg. / ˌ s ɛ f ə l ə ˈ s p ɔːr ɪ n, ˌ k ɛ-,-l oʊ-/ [1] [2]) are a class of β-lactam antibiotics originally derived from the fungus Acremonium, which was previously known as Cephalosporium. [3] Together with cephamycins, they constitute a subgroup of β-lactam antibiotics ...
Cephalosporins (Fourth generation) Cefepime: Maxipime: Covers pseudomonal infections. Gastrointestinal upset and diarrhea; Nausea (if alcohol taken concurrently) Allergic reactions; Same mode of action as other beta-lactam antibiotics: disrupt the synthesis of the peptidoglycan layer of bacterial cell walls. Cephalosporins (Fifth generation ...
Cephalosporin C is an antibiotic of the cephalosporin class. It was isolated from a fungus of the genus Acremonium and first characterized in 1961. [ 1 ] Although not a very active antibiotic itself, synthetic analogs of cephalosporin C, such as cefalotin , became some of the first marketed cephalosporin antibiotic drugs.
Like most other cephalosporins, cefalexin is not metabolized or otherwise inactivated in the body. [26] [31] The elimination half-life of cefalexin is approximately 30 to 60 minutes in people with normal renal function. [31] [30] Therapeutic levels of cefalexin with oral administration are maintained for 6 to 8 hours. [30]
Ceftriaxone, sold under the brand name Rocephin, is a third-generation cephalosporin antibiotic used for the treatment of a number of bacterial infections. [4] These include middle ear infections, endocarditis, meningitis, pneumonia, bone and joint infections, intra-abdominal infections, skin infections, urinary tract infections, gonorrhea, and pelvic inflammatory disease.

Cefodizime is a 3rd generation cephalosporin antibiotic with broad spectrum activity against aerobic gram positive and gram negative bacteria. Clinically, it has been shown to be effective against upper and lower respiratory tract infections, urinary tract infections, and gonorrhea.
Cefotiam is a parenteral third-generation cephalosporin antibiotic. It has broad-spectrum activity against Gram-positive and Gram-negative bacteria. As a beta-lactam, its bactericidal activity results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins. It was patented in 1973 and approved for medical use in ...
The mean steady-state volume of distribution in healthy adult males after a single 1.5 g IV dose is 13.5 L for ceftolozane and 18.2 L for tazobactam, which is similar to extracellular fluid volume. Tissue distribution of ceftalozone-tazobactam is rapid and shows good penetration into the lung, rendering it an ideal treatment for bacterial ...
